SUBSTANCE: invention relates to a device (1) to be connected to a floor cleaning machine using liquid in its operation. According to the invention, the combined hub (5) for installation of the machine brush/disc (6) performs three functions, namely: a) brush/disc retention hub, b) distributor of liquid supplied into the machine in a radial direction from the outside to the hub centre, and c) distributor of vacuum supplied into the machine for suction of washing liquid therefrom.

SUBSTANCE: invention relates to a dirt-capturing device for a machine for cleaning floor, intended to capture fluid from the floor to be cleaned, which comprises a support and at least one scraper element to clean the floor surface, with the support and at least one scraper element form borders of the suction channel ending in the suction neck traversed by the suction flow, which free cross-sectional area decreases in the longitudinal direction of the dirt-capturing device from the suction neck, at least on one section of the channel, which is different in the fact that in the suction channel (52) at least one element (70, 72) narrowing the channel is located, which is manufactured separately from the support (36).

EFFECT: increased speed of suction flow due to element of the channel narrowing.

SUBSTANCE: cleaner is designed for wet and dry cleaning the uncovered floor surfaces. The cleaner contains the control lever pivotally connected to the bottom, return system with wet and dry cleaning suction nozzles mounted on the bottom, wet and dry dust return tank, control air duct started from each dry cleaning suction nozzle and wet cleaning suction nozzle to the return tank. The control lever or the bottom accommodates the mounted electromotor/fan assembly to generate control air flow in the control air duct, at least, from dry cleaning suction nozzle or wet cleaning suction nozzle to the return tank. The control air duct starts from each dry cleaning suction nozzle and wet cleaning suction nozzle to the return tank. The control air duct contains the mounted deflector moving between dry cleaning suction position and wet cleaning suction position for selective, at least, partial blocking of the control air flow from wet cleaning suction nozzle and dry cleaning suction nozzle, respectively to the return tank. Besides there is a mounted mechanism connected with the deflector on the control lever to enable the deflector to move between dry cleaning suction position and wet cleaning suction position. According to the performance version the cleaner contains the initiator mounted on the bottom and moving vertically between low position for contact interaction with the cleaned surface and lifted position over the cleaned surface for selective excitation. The cleaner can contain the cut-off valve mounted in the return tank and used to prevent hydrodynamic connection of electromotor/fan assembly and the return tank if liquid level in the return tank reaches the first preset value once the control lever is in the first position forward from the vertical position, and the second preset value different from the first one once the control lever is in the second position back from the vertical position. According to the performance version provided, the cleaner is supplied with bothway holder on the control lever, with the first part adapted for convenient holding with the user hand as the control lever is in dry cleaning suction position, and the second part adapted for convenient holding with the user hand essentially in the similar relative position as the control lever is in wet cleaning suction position.

EFFECT: improved convenience in using the cleaner with simplified design and without auxiliary means.

SUBSTANCE: invention is related to device in the form of circular disc-like cleaning element, which is intended for performance of cleaning with the help of cleaning machine. The element has several deepenings that are distributed on its active cleaning surface in accordance with desired pattern. Polishing elements contain technical diamonds and are located in the mentioned deepenings. Each polishing element is enclosed into thermoplastic holder, which is installed and spring-loaded on the cleaning element. When the disc is pressed, the polishing elements slightly touch the cleaned surface. The method stipulated for surface processing with the mentioned device with further wet cleaning with application of traditional cleaning element.

EFFECT: more efficient cleaning and polishing of cleaned surface is achieved.

SUBSTANCE: proposed vacuum cleaner has housing, brush unit, brush rotating in contact with surface to be cleaned, water discharge tip and front and rear blocking parts. Dirt and dust suction hole is pointed to surface under cleaning, flow-through communicates with main housing and limits dirt suction channel. Front and rear blocking parts are made in front and rear parts of brush unit on its lower surface for selective opening or closing of dirt suction channel under action of friction force appearing at engagement with surface under cleaning. Front blocking part contains closing shield in form of plate to close dirt suction channel in front part of brush unit, turnable axle made on opposite ends of closing shield and attached for turning to brush unit, and turnable projection in form of sector on side of closing shield whose bow-like section passes from leading edge of closing shield so that leading edge of closing shield recedes from surface under cleaning when bow-like section comes in contact with surface under cleaning. Rear blocking part is made behind rotating brush and it contains upper part secured in groove for accommodating rear blocking part made in brush unit and rear closing shield with flat surface and projecting surface with bosses equally spaced on surface. Pressure is applied from side of surface under cleaning on part of each leading end, flat surface or projecting surface selectively, depending on direction of movement of brush unit. With vacuum cleaner moved forward, its front blocking part opens dirt suction channel, rear blocking part closes dirt suction channel and rear closing shield flexes so that pressure from side of surface under cleaning is applied to flat surface. With vacuum cleaner moving backwards, front blocking part closes dirt suction channel, and rear blocking part opens dirt suction channel and closing shield flexes so that pressure from side of surface under cleaning is applied to projecting surface.
